After Effects Notes

...artist-animators. With the more modern forms of colour film introduced in the early 1930s, opaque paints and coloured inks could be used on the cels. Cel animation required the use of a so-called rostrum camera, which photographs downward onto the background with its series of superimposed cel layers pegged into place to secure accurate registration.

After Effects once again proves its incredible usefulness

Do a RAM preview for realtime preview of your After Effects animation before actually rendering to double check how everything goes.

Layer >> 3D Layer

Now 3 Axises are available

Effects>> Distort>> Offset (Infinity Moving Background)

Must however consider the seamlessness

Use Photoshop to clean that up

Furthest layer should move the least, nearest should move the most

Motion blur only works on the edge of shapes, and so does not effect the offset
